Some have fun of me because I'm often using old stuff, but I don't even remember having used an application that made use of mandatory locking. I remember having enabled it myself in my kernels long ago after discovering its existence in the man pages, just to test it. It doesn't rule out the possibility that it exists somewhere though, but I think that the immediate removal combined with the big fat warning in previous branches should be largely enough to avoid the last minute surprise.
